title: 2,3-Dihydro-6,7-dichloro-pyrido[2,3-b]pyrazine-8-oxide as selective glycine antagonist with in vivo activity.
abstract: 2,3-Dihydro-6,7-dichloro-pyrido[2,3-b]pyrazine-8-oxide was synthesized and evaluated for in vitro/in vivo antagonistic activity at the strychnine insensitive glycine binding site on the NMDA receptor revealing it to be a useful tool to evaluate the effectiveness of glycine antagonists in vivo.
